REMOTE CONTROL COMBINATION LOCK Filed Jan. 3, 1954 2 Sheets-Sheet 2 6 INVENTOR Z7 W!TNESSES BY Jose/171 CJ/[mma ATTORNEYS of times to cause the ratchet gear 43 and. the gear 31 to rotate clockwise in an obvious manner by the pawl 53, thereby causing one of the pins on the tumbler 33 to act on one of the pins on the tumbler 34. In this manner, by alternately manipulating the buttons 68 and 69 each a-predetermined number of times, the tumblers may be rotated progressively until all of them move in unison to bring the recesses 37 in registry, to allow the nose 72 of the dog 70 to be projected into the recesses 3'7, so registered, by the spring '74, and incidentally allow the rack 25 to mesh with the gear 31, The button 68 may then be manipulated a predetermined number of times, causing the ratchet gear 42 and gear 31 to rotate in a counterclockwise direction, as indicated by the arrow in Fig. 4, thereby causing the rack 25 to move tangentially to the left, and through the intervention of the link 28 and lever 21, causing the retraction of the bolts 17. In this manner, the door 10 will be unlocked. To again lock the door, it will be necessary to manipulate the button 68 which will cause the rack 25 to move tangentially to the right bythe means and in the manner described hereinbefore.

If desired, the parts of the lock may be enclosed by a casing 82, which is slotted, as at 83, to accommodate the bolt 17. The casing 82 is secured, as at 84, to the plate 23.

I claim:

1. In a look, a locking bolt mounted to be projected into a locking position and also to be retracted from said position, an assembly of tumblers each having a marginal recess, said tumblers being movable to bring their recesses in registry with each other, a gear rotated by said assembly, a rack movable into and out of mesh with said gear, a movable dog carried by said rack, said dog being engageable in said recesses by resilient means when the recesses are in registry, to allow said rack tomesh with said gear, and means connecting said rack and bolt to project and retract the bolt in response to the rotation of said assembly after the dog is engaged as aforesaid.

2. In a look, a locking bolt mounted to be projected into a locking position and also to be retracted from said position, an assembly of tumblers each having a marginal recess, said tumblers being movable to bring their recesses in registry with each other, a gear rotated by said assembly, a rack movable into and out of mesh with said gear, a movable dog carried by said rack, said dog being engageable in said recesses by resilient means when the recesses are in registry, to

allow said rack to mesh with said gear, means connecting said rack and bolt to project and retract the bolt in response to the rotation of said assembly after the dog is engaged as aforesaid, said assembly causing the dog to be disengaged from the'registered recesses in responseto rotation of said assembly in the bolt retracting operaforesaid, said last means engaging in a notch in the rack when the latter is in bolt projected position, to prevent retraction of the bolt, subject to the reentry of the dog'in the registered recesses.

3. In a look, a locking bolt mounted to be projected into a locking position and also to be retracted from said position, an assembly of tumblers each having a marginal recess, said tumblers being movable tobring their recesses in registry with each other, a gear rotated by said assembly, a rocker, a rack pivotally connected with said rocker so as to be movable into and out of mesh with said gear, a movable dog carried by said rack, said dog being engageable in said recesses by resilient means when the recesses are in registry,'to allow said rack to mesh with said gear, and means connecting said rack and bolt to project and retract the bolt in response to the rotation of said assembly after the dog is engaged as aforesaid. I

4. In a look, a lever, locking bolts connected with said lever to be operated thereby, a rocker arm, a link whose opposite ends are pivotally connected respectively with said lever and rocker arm, a member having one end pivotally connected with thepivotal connection of said lever and rocker arm, and means to operate said member to operate said bolts throughthe intervention of said link and lever.

5. In a look, a lever, locking bolts connected with said lever to be operated thereby, a link having one end pivotally connected with said lever, a member having one end pivotally connected with the remaining end of said link, and 2 nected with the remaining end of said link, and

means to operate said member to operate said .bolts through the intervention of said link and lever, said means including a pivoted dog carried by said member.
